Although, I don't agree with everything I find some truth in the article. The only time I need a phone number is the first time I enter someone in my phone. Otherwise, it's just a username after that point. Skype recognized this and I see no reason we can't get rid of phone numbers all together in the next 10 years. My only fear is that the legacy systems of the past will carry on because of the "sacred cow"...sort of like how racism keeps hanging on with older generations while the new generation moves on silently thinking how crazy the older generation is.
